I think it is reasonable that plugins/scripts can create resources that are outside the scope of the plugin/script itself. The developer just needs to be aware that's what is happening. Ok so now I'm aware of it. Cool. Its somewhat of an interesting issue.
Anyway, it seems nobody has the time and energy to really work on the needed changes in script-fu to make it a viable programming environment.

In script-fu it shouldn't be possible to enerate memory leaks, but a plug-in (like script-fu) can easily create memory lekas within the main gimp application. This is not easy to solve, and the question is wether it should be "solved" for all cases (I can think of a lot of cases where holding images inside the gimp for cahcing reasions makes a lot of sense, without them being actively referenced).
